添付図面を参照して、本発明の好適な実施形態について説明する。なお、各図において、同一の符号を付したものは同一又は同様の構成を有する。 Preferred embodiments of the present invention will be described with reference to the accompanying drawings. In each figure, those with the same reference numerals have the same or similar configurations.

図１を参照し、実施形態に係る運転支援システムの構成について説明する。運転支援システム１００は、例えば、ユーザが使用する情報端末１と、データセンタ等に配置されるサーバ２と、を含む。情報端末１及びサーバ２は、例えば無線ネットワークを含むネットワークを介して相互に通信できるように構成される。 The configuration of the driving support system according to the embodiment will be described with reference to FIG. The driving support system 100 includes, for example, an information terminal 1 used by a user and a server 2 arranged in a data center or the like. The information terminal 1 and the server 2 are configured to be able to communicate with each other via a network including, for example, a wireless network.

図１に示す情報端末１は、例えば、カーナビゲーション装置、ナビゲーション機能付き車載装置、スマートフォン等の端末装置である。情報端末１は、機能的な構成として、例えば、制御部１１と、入力部１２と、出力部１３と、記憶部１４と、通信部１５とを有する。情報端末１は、物理的な構成として、例えば、ＣＰＵ（Ｃｅｎｔｒａｌ Ｐｒｏｃｅｓｓｉｎｇ Ｕｎｉｔ）及びメモリを含む制御ユニット、操作部、ディスプレイ、スピーカ、記憶ユニット、通信ユニット等を備えて構成される。ＣＰＵがメモリに格納された所定のプログラムを実行することにより、制御部１１、入力部１２、出力部１３、記憶部１４及び通信部１５の各機能が実現する。 The information terminal 1 shown in FIG. 1 is, for example, a terminal device such as a car navigation device, an in-vehicle device with a navigation function, or a smartphone. The information terminal 1 has, for example, a control unit 11, an input unit 12, an output unit 13, a storage unit 14, and a communication unit 15 as functional configurations. As a physical configuration, the information terminal 1 includes, for example, a control unit including a CPU (Central Processing Unit) and a memory, an operation unit, a display, a speaker, a storage unit, a communication unit, and the like. When the CPU executes a predetermined program stored in the memory, the functions of the control unit 11, the input unit 12, the output unit 13, the storage unit 14, and the communication unit 15 are realized.

サーバ２は、機能的な構成として、例えば、地点特定部２１と、状況判定部２２と、注意喚起部２３と、記憶部２４と、通信部２５とを有する。サーバ２は、物理的な構成として、例えば、ＣＰＵ及びメモリを含む制御ユニット、記憶ユニット、通信ユニット等を備えて構成される。ＣＰＵがメモリに格納された所定のプログラムを実行することにより、地点特定部２１、状況判定部２２、注意喚起部２３、記憶部２４及び通信部２５の各機能が実現する。各機能のうち地点特定部２１、状況判定部２２及び注意喚起部２３について、以下に詳細に説明する。 As a functional configuration, the server 2 has, for example, a point specifying unit 21, a situation determination unit 22, a warning unit 23, a storage unit 24, and a communication unit 25. As a physical configuration, the server 2 includes, for example, a control unit including a CPU and a memory, a storage unit, a communication unit, and the like. When the CPU executes a predetermined program stored in the memory, the functions of the point specifying unit 21, the situation determination unit 22, the alerting unit 23, the storage unit 24, and the communication unit 25 are realized. Of the functions, the point specifying unit 21, the situation determination unit 22, and the alerting unit 23 will be described in detail below.

地点特定部２１は、複数の車両から収集した車両情報に基づいて、車両の速度が上昇しやすい地点を特定する。車両情報は記憶ユニットに記憶される。 The point specifying unit 21 identifies a point where the speed of the vehicle is likely to increase based on the vehicle information collected from a plurality of vehicles. Vehicle information is stored in the storage unit.

車両情報には、例えば、車両の位置情報、車両の状態情報、車両の属性情報、及びデータを収集した時刻等が含まれる。車両の状態情報には、例えば、車両の速度情報及びアクセル開度情報等が含まれる。 The vehicle information includes, for example, vehicle position information, vehicle state information, vehicle attribute information, time when data was collected, and the like. The vehicle state information includes, for example, vehicle speed information, accelerator opening degree information, and the like.

地点特定部２１は、車両情報に基づいて、車両の速度が上昇しやすい地点を特定する。車両の速度が上昇しやすい地点として、例えば、下り坂、平坦な直線道路等が該当する。 The point specifying unit 21 identifies a point where the speed of the vehicle is likely to increase based on the vehicle information. Examples of points where the speed of the vehicle tends to increase include downhill slopes and flat straight roads.

図２を参照して、具体的に説明する。図２は、ある車両における、車両の高度Ｈ、車両の速度Ｖ及びアクセル開度Ａの推移を表すグラフである。車両の高度Ｈ、車両の速度Ｖ及びアクセル開度Ａは、車両情報に基づいて定めることができる。 A specific description will be given with reference to FIG. FIG. 2 is a graph showing changes in the altitude H of the vehicle, the speed V of the vehicle, and the accelerator opening degree A in a certain vehicle. The altitude H of the vehicle, the speed V of the vehicle, and the accelerator opening degree A can be determined based on the vehicle information.

図２に示す地点Ｐａは、下り坂である。地点Ｐａは、車両の高度Ｈが低下し、車両の速度Ｖが上昇し、かつアクセル開度Ａの変化がほとんどない地点となる。このように、下り坂は、アクセルを踏まなくても速度が上昇する傾向がある。 The point Pa shown in FIG. 2 is a downhill. The point Pa is a point where the altitude H of the vehicle decreases, the speed V of the vehicle increases, and the accelerator opening degree A hardly changes. In this way, the downhill tends to increase in speed without stepping on the accelerator.

したがって、地点特定部２１は、車両情報に基づいて、車両の高度Ｈが所定値以上低下し、車両の速度Ｖが所定速度以上上昇し、かつアクセル開度Ａの変化が所定範囲内である地点が存在する場合に、下り坂であると判定し、その地点Ｐａを車両の速度が上昇しやすい地点であると特定する。 Therefore, the point specifying unit 21 is a point where the altitude H of the vehicle decreases by a predetermined value or more, the speed V of the vehicle increases by a predetermined speed or more, and the change of the accelerator opening A is within a predetermined range based on the vehicle information. If is present, it is determined that the vehicle is downhill, and the point Pa is specified as a point where the speed of the vehicle is likely to increase.

図２に示す地点Ｐｂは、平坦な直線道路である。地点Ｐｂは、車両の高度Ｈの変化がほとんどなく、車両の速度Ｖが上昇し、かつアクセル開度が大きくなる地点となる。このように、平坦な直線道路は、アクセルを踏み込んで加速をしてしまう傾向がある。 The point Pb shown in FIG. 2 is a flat straight road. The point Pb is a point where the altitude H of the vehicle hardly changes, the speed V of the vehicle increases, and the accelerator opening becomes large. In this way, a flat straight road tends to accelerate by depressing the accelerator.

したがって、地点特定部２１は、車両情報に基づいて、車両の高度の変化が所定範囲内であり、車両の速度が所定速度以上上昇し、かつアクセル開度が所定値以上大きくなる地点が存在する場合に、平坦な直線道路であると判定し、その地点Ｐｂを車両の速度が上昇しやすい地点であると特定する。 Therefore, the point specifying unit 21 has a point where the change in the altitude of the vehicle is within a predetermined range, the speed of the vehicle increases by a predetermined speed or more, and the accelerator opening degree increases by a predetermined value or more, based on the vehicle information. In this case, it is determined that the road is a flat straight road, and the point Pb is specified as a point where the speed of the vehicle is likely to increase.

図１の説明に戻る。状況判定部２２は、地点特定部２１により特定された地点から車両が所定距離進行する範囲内に、車両の減速要因が存在するか否かを判定する。車両の減速要因には、例えば、一時停止が存在すること、道幅が狭くなること、渋滞していること、及び車両の速度が低下しやすい地点が存在すること等が含まれる。 Returning to the description of FIG. The situation determination unit 22 determines whether or not a vehicle deceleration factor exists within a range in which the vehicle travels a predetermined distance from the point specified by the point identification unit 21. The deceleration factors of the vehicle include, for example, the existence of a temporary stop, the narrowing of the road width, the congestion, and the existence of a point where the speed of the vehicle is likely to decrease.

車両の進行方向に車両の減速要因が存在するか否かは、例えば、地図情報、交通情報等に基づいて判定することができる。 Whether or not a vehicle deceleration factor exists in the traveling direction of the vehicle can be determined based on, for example, map information, traffic information, and the like.

注意喚起部２３は、減速要因が存在する場合に、その減速要因が存在することを運転者に注意喚起する。注意喚起は、例えば、「下り坂が続いた後に、渋滞があります。スピードを落として運転しましょう」というメッセージ、又は「ここで加速しても、この先一時停止があります」というメッセージを、情報端末１のスピーカから出力させることや、情報端末１のディスプレイに表示させることにより行う。 When the deceleration factor exists, the caution unit 23 alerts the driver that the deceleration factor exists. The alert is, for example, the message "There is a traffic jam after the downhill continues. Let's drive at a slower speed" or the message "Even if you accelerate here, there will be a stop in the future" on the information terminal. It is performed by outputting from the speaker of 1 or displaying on the display of the information terminal 1.

図３を参照して、実施形態における運転支援システム１００の動作の一例について説明する。 An example of the operation of the driving support system 100 in the embodiment will be described with reference to FIG.

最初に、地点特定部２１は、複数の車両から収集した車両情報に基づいて、車両の速度が上昇しやすい地点を特定する（ステップＳ１０１）。 First, the point specifying unit 21 identifies a point where the speed of the vehicle is likely to increase based on the vehicle information collected from the plurality of vehicles (step S101).

続いて、状況判定部２２は、上記ステップＳ１０１で特定された地点から車両が所定距離進行する範囲内に、車両の減速要因が存在するか否かを判定する（ステップＳ１０２）。この判定がＮＯである場合（ステップＳ１０２；ＮＯ）には、処理を上記ステップＳ１０１に移行する。 Subsequently, the situation determination unit 22 determines whether or not the deceleration factor of the vehicle exists within the range in which the vehicle travels a predetermined distance from the point specified in step S101 (step S102). If this determination is NO (step S102; NO), the process proceeds to step S101.

一方、上記ステップＳ１０２において、特定された地点から車両が所定距離進行する範囲内に、車両の減速要因が存在すると判定された場合（ステップＳ１０２；ＹＥＳ）に、注意喚起部２３は、減速要因が存在することを運転者に注意喚起する（ステップＳ１０３）。そして、処理を上記ステップＳ１０１に移行する。 On the other hand, when it is determined in step S102 that a vehicle deceleration factor exists within a range in which the vehicle travels a predetermined distance from the specified point (step S102; YES), the alerting unit 23 has a deceleration factor. The driver is alerted to the existence (step S103). Then, the process shifts to the above step S101.

前述したように、実施形態における運転支援システム１００によれば、複数の車両から収集した車両の位置情報及び車両の状態情報を含む車両情報に基づいて、車両の速度が上昇しやすい地点を特定し、その特定した地点から車両が所定距離進行する範囲内に、車両の減速要因が存在するか否かを判定し、車両の減速要因が存在する場合に、その減速要因が存在することを運転者に注意喚起することができる。 As described above, according to the driving support system 100 in the embodiment, the point where the speed of the vehicle is likely to increase is specified based on the vehicle information including the vehicle position information and the vehicle state information collected from a plurality of vehicles. , It is determined whether or not the vehicle deceleration factor exists within the range in which the vehicle travels a predetermined distance from the specified point, and if the vehicle deceleration factor exists, the driver determines that the deceleration factor exists. Can be alerted to.

つまり、車両の速度が上昇しやすい地点と、その地点の先にある減速要因になる状況とに基づいて、その状況に適合した注意喚起を運転者に対して行うことが可能となる。 That is, it is possible to alert the driver according to the situation based on the point where the speed of the vehicle is likely to increase and the situation which becomes a deceleration factor ahead of the point.

それゆえ、実施形態における運転支援システム１００によれば、注意喚起により運転者の利便性を向上させることができる。 Therefore, according to the driving support system 100 in the embodiment, it is possible to improve the convenience of the driver by calling attention.
